“…Their disposal has become a severe social and environmental issue in several countries (Ferguson [5]), thus highlighting the importance of their recycling and reuse. In many European countries, the recycling of demolition waste dates back to the end of World War II, being widely investigated for the past few decades (Hansen [8]). …”

Abstract:From the viewpoint of environmental preservation and effective utilization of resources, it is beneficial and necessary to reuse wastes, for example, concrete, as the recycled aggregates for new materials. In this work, the dynamic behavior of such aggregates under low frequency torsional loading is studied. Results show that the properties of such artificial soils match with those reported in the literature for specific natural soils.

“…Flexure strength: -Studies reported maximum 10% to 24% reduction in flexure strength has been reported when different level of recycled aggregate is used to produce concrete [7,19,31,23]. When compared to normal concrete different water cement ratio was investigated than a considerable difference in the flexural strength has been reported [34].…”

“…It was reported that reduction in strength is mostly in between 12% to 30% but sometimes till 60 % with 100% replacement of recycled aggregate [7,9,18,19]. Sometimes the strength parameter get influenced by un-hydrated coating of parent concrete over recycled aggregate as due to the curing condition may unable to complete the hydration process in parent concrete [11].…”

Today's modern era is demanding more and more infrastructure development and with the increasing demand of infrastructure, the demand and supply chain of the construction material are getting affected. With increasing pace of development, a great concern is required towards environment as well as natural resources. In this paper, behavior of concrete utilizing recycled aggregate is critically reviewed. Properties of recycled aggregate are discussed at first, followed by the properties of concrete utilizing recycled aggregate. It has been reported that recycled aggregate was found useful if the replacement level is about 30% .This type of concrete has been used in many applications. Recycled aggregate can be seen as future material which will be eco -friendly and will decrease in project cost.

“…When dealing with new RA concrete compositions, the high water absorption of RA particles [10] must be taken into consideration to achieve the same concrete mix hydration designed for NA concrete composition. Equation 2 allows the calculation of the water dosage necessary to hydrate the RA concrete mix to the same level as NA concrete composition.…”

Abstract. The paper presents the results and conclusions of investigations aiming to encourage the use of recycled materials, namely recycled aggregates (RA) and recycled steel fibers (RSF), in the construction of durable, economic and environmental friendly rigid pavements. To minimize and limit the negative effect of RA on the mechanical properties of cement concrete pavements, the research program considered both, development of technical solutions to improve the performance characteristics of RA particle, and RSF disperse reinforcement of concrete mixtures. Roller compacted concrete (RCC) cylindrical and prismatic test specimens manufactured with natural aggregates (NA) and original/performance improved RA have been subjected to flexure and compressive testes to evaluate the influence and contribution of developed technologies. Finally, guidelines and considerations for the use of RA in RCC and plain cement concrete (PCC) pavements are drawn.
